Hygrophila didynama

An obscure south-central African Hygrophila known from only a handful of wild records in Zambia, Zimbabwe and Malawi at about 950–1400 m. Like its relatives it is most likely a herb of seasonally wet ground, so it wants warm, bright, wet conditions in the rainy season and tolerates a cooler, drier winter.

Where it grows wild

Little is published on this species; Hygrophila of the Zambezian plateau typically grow in dambos, marshes and stream margins that flood in the rains and dry out later, so its habitat is inferred from the genus.

Recorded at 950–1400 m, median 1000 m.
